Clone commander Doom commanded a unit of clone troopers alongside Jedi Generals Tiplar and Tiplee. They utilized blast shields of their own variation. Troopers of this unit were also armed with Z-6 rotary blaster cannons and Electro Magnetic Pulse grenades.
In 19 BBY, the Republic battled the Separatists on a space station ring around the planet Ringo Vinda. Led by Jedi Generals Tiplar and Tiplee and Commander Doom, this unit advanced and fought alongside the 501st Legion. During the battle, the unit became severely depleted. Attempting to break the deadlock, the Republic made a desperate push toward the Seperatists and managed to reach the communications center.
There, they discussed a battle plan to seize the Separatist command center. ARC trooper CT-5555 ("Fives") and CT-5385 ("Tup") were ordered to rally ten of their men to reinforce Doom's unit as they advanced. But as Republic troops reached the command center, trooper Tup fell into a trance and, before anyone could react, shot Tiplar dead.
